1.	A solid sphere is suspended from a wire and is made to execute torsional oscillations with a period of 2 second. The torque required to twist the wire through unit radian is 6 xx10^(-2)N/m. Calculate the moment of inertia of the sphere about the axis of rotation.
Answer» SOLUTION :`I=CT^2//4pi^2=6xx10^(-2)xx4//4pi^2=0.61xx10^(-2)KG m^2`
